Abstract

In apparatus for continuously monitoring partial discharge in high voltage electrical equipment thereby to give advance warning of impending breakdown of solid-insulated components (e.g. capacitors 11 to 16), means are provided to distinguish electrical signals indicative of partial discharge from those resulting from noise or external transients. Current pulses in the various partial discharge paths are detected by detectors (21 to 26), and by means of solid-state circuitry (40, 41) their relative polarities are compared and an appropriate signal is made according to the comparison.
